Darkgunman-3 I’m thinking of bring the Orc Blood Lust special rule into the wider rules. As you may know Blood Lust works a lot like Frenzy, but you can take a DC to try and control it, and that is how it will work for the Vampires.
Also the Manticore is one of the mid sized monsters and will be roughly the same size as the Elf Roc or Herlanceian Griffin, but with just more Bite! Also I am thinking of giving it poisoned attacks with them having a Scorpion’s tail.
